What Is a Moment Connection?

What is a moment connection? A moment connection in structural engineering is a joint that allows the transfer of bending moment forces between a column and beam (or any other two members). If a child member (a beam) has some internal moment, the connection should be able to transmit the load due to that moment.

What Is a Moment Connection?

A moment connection is a type of connection used in structural engineering to connect beams or columns to resist moment forces. Moment connections are typically used in trusses, beams, and rigid frames. The connection transfers both shear and moment between the members.

The most common type of moment connection is the bolted connection. Bolted moment connections are made by attaching a plate to the end of the beam or column and then bolting the plate to the column or beam. The bolts are usually arranged in a triangle or square pattern.

Welded moment connections are made by welding the plate to the end of the beam or column. Welded connections are stronger than bolted connections but are more expensive to make.

Slotted moment connections are made by attaching a plate to the end of the beam or column and then slotting the plate into the column or beam. The plate is then welded or bolted in place. Slotted connections are stronger than bolted or welded connections but are more expensive to make.

The size and type of moment connection depend on the loads that the connection will be subjected to. The connection must be strong enough to resist the maximum force that will be applied to it. The connection must also be able to resist the moments that will
